It is not only producing high quality, unique
3D-measurements of amplifiers, it is also an
integrated part of the development and
production cycle at the world leading audio
manufacturers.
The PowerCube Measuring
System
Our PowerCube Stand Alone System allows you to
test all your new audio amplifier constructions,
conventional or Class D.
Do you think Class D is the solution for
stability? You'd better check it before you go
into production! For several decades it has been
common knowledge that a loudspeaker is all but
an 8 ohm resistor. Playing an 8 ohm speaker may
hit the amplifier with impedances as low as 2
ohms, and with severe phase shifts as well -
both capacitive and inductive.

| The PowerCube Option - Water Cooled Load Box
is an option for very high power measurements
according to CEA2006. The system uses the
concept of electronic loads to simulate reactive
loads and can thus measure very large amplifiers. |

"What Is A PowerCube?"
"A PowerCube is a unique piece of test equipment
that measures an amplifier's output voltage
across 20 impedances from 1 to 8 ohms. Developed
by AudioGraph, the PowerCube adheres strictly to
the IHF 202 signal standard to create
informative three-dimensional (3D) graphs of
voltage versus impedance and phase at a single
frequency, typically 1 kHz."
(excerpt from The Clarion Product Training
Manual)
Are you designing or evaluating audio amplifiers?
Try out the PowerCube! In just a couple of
minutes it measures all the relevant attributes,
and presents the result in a comprehensible and
easy-to-read 3-D diagram. |
